John Krafcik is an American engineer who coined the term lean production, generalizing the Toyota Production System into the framework that reshaped automotive and industrial manufacturing worldwide. While completing a management thesis at MIT's Sloan School, and drawing on his earlier work as a quality engineer at NUMMI, the Toyota-General Motors joint venture in Fremont, California, Krafcik compared assembly plants across the auto industry and, in his 1988 Sloan Management Review article Triumph of the Lean Production System, used lean to name plants achieving high output and quality with far less buffer inventory, indirect labor and job specialization than traditional mass production required. His MIT colleagues James Womack, Daniel Jones and Daniel Roos popularized the term worldwide in their 1990 book The Machine That Changed the World. Krafcik went on to a long engineering and executive career including Chief Engineer at Ford, CEO of Hyundai Motor America (2008-2013), and CEO of Waymo, Alphabet's self-driving car company (2015-2021), where he launched the first fully autonomous commercial ride-hailing service; he later joined Rivian's board of directors and continues to advise mobility and robotics companies.

Who coined the term lean production, and what experience shaped it?
Krafcik coined lean production after working at NUMMI and comparing auto plants at MIT.
John Krafcik coined the term lean production. He began his career as a quality and manufacturing engineer at NUMMI, the General Motors and Toyota joint venture in Fremont, California, from 1984 to 1986. He later compared assembly plants across the auto industry while completing a management thesis at MIT's Sloan School, and used lean to name plants that achieved high output and quality with far less buffer inventory, indirect labor and job specialization than traditional mass production required. His MIT colleagues James Womack, Daniel Jones and Daniel Roos popularized the term in their 1990 book The Machine That Changed the World.
